Declares which child group contains a path leading to a NXdata group.

It is recommended (as of NIAC2014) to use this attribute to help define the path to the default dataset to be plotted. See https://www.nexusformat.org/2014_How_to_find_default_data.html for a summary of the discussion.

The manufacturer of the capillary. This is actually important as it may have an impact on performance.

maximum_incident_angle: (optional) NX_FLOAT {units=NX_ANGLE}

accepting_aperture: (optional) NX_FLOAT {units=NX_ANGLE}

working_distance: (optional) NX_FLOAT {units=NX_LENGTH}

focal_size: (optional) NX_FLOAT

The focal size in FWHM

depends_on: (optional) NX_CHAR

NeXus positions components by applying a set of translations and rotations to apply to the component starting from 0, 0, 0. The order of these operations is critical and forms what NeXus calls a dependency chain. The depends_on field defines the path to the top most operation of the dependency chain or the string “.” if located in the origin. Usually these operations are stored in a NXtransformations group. But NeXus allows them to be stored anywhere.

gain: (optional) NXdata

The gain of the capillary as a function of energy

transmission: (optional) NXdata

The transmission of the capillary as a function of energy

TRANSFORMATIONS: (optional) NXtransformations
